Strictly speaking, the Nokia N9 does not run MeeGo 1.2 as its operating system. It instead runs what Nokia refers to as a "MeeGo instance". During the development of Harmattan (previously marketed as Maemo 6), Nokia and Intel merged their open source projects into one new common project called MeeGo. Not to postpone the development schedule, Nokia decided to keep the "core" of Harmattan, such as middleware components (GStreamer) and packaging manager (Harmattan uses deb not RPM). Nonetheless, Harmattan is designed to be fully API compatibility with MeeGo 1.2 via Qt. As far as end users and application developers are concerned, the distinction between Harmattan and MeeGo 1.2 is minimal. Since all marketing effort would have been directed to "MeeGo", Nokia dropped the Maemo branding to adopt MeeGo as to not confuse customers.
